• Performance & Reliability: Enhancing the robustness and efficiency of our current systems.
• Security Integration: Embedding security best practices early in the development lifecycle with a DevSecOps "shift-left" mindset.
• Automation: Eliminating TOIL to boost efficiency and ensure sustainable operations.

• The ability to enable seamless, self-service deployments through robust and reliable continuous delivery pipelines.
• A foundational understanding of IT security concepts (Penetration Testing, lateral movement, XSS, SQLi, tc.).
• A genuine willingness to share knowledge with and learn together.

Bonus Points If You Have:

• Production experience with Kubernetes.
• Exposure to AWS Billing and cloud cost optimization.
